Application filed August 12, 1855. Serial No. 174,191. (No model.)

shaft, I, which carries at its lower end a gear, On the opposite side ofthe machine, Fig. 3,

upon the shaft 1), is a small pulley, d, that is connected by a belt, 0,Figs. 1 and 2, to a large pulley, e, that is geared to drive the lowerfeed-rolls. The pulley e carries a pinion, f, that drives a gear-wheel,g, having a pinion, h, for actuating the gear 8 of the front lowerfeed-roll, which gear 5 in turn actuates an intermediate gear, t, fordriving the gear a of the back lower roll.

The gearing for driving the upper and lower sets of feed-rollsindependent of each other is shown in Fig. 4, and the position of theseveral gears is shown by broken lines in Figs. 1 and 2, the gears fordriving the upper rolls being indicated by lines broken at longintervals, while the gears for driving the lower rolls are indicated bylines broken at short in tervals. By thus driving the upperand lowerrolls independently upon opposite sides of the machine I am enabled todispense entirely with expansion-gearing, and can employ to advantagelighter trains of gears than usual.

The roll-belts c c are tightened or slackened to start or stop the feedby means of two tighteners, N N, attached to arms 0 O, that areadjustably mounted on a cross-shaft, w, by means of set-screws yy, so asto permit adjustment of each tightener to the state of its own belt.Both tighteners are manipulated at the same time by a lever, P, attachedto the shaft 20, and having a spring-locking pawl for engagement with arack, Q, by which the tighteners are held in contact with or away fromthe belts.

On the shaft 1) are pulleys z 2, that carry belts R R, for actuating thematcher-heads S S, which, together with their usual accompanyments, maybe arranged near the delivery end of the machine. These matcher-headsare adj ustably supported in the ordinary manner, as shown in Fig. 4.

\Nhen the machine is to be used for tongueing and grooving or matchinglumber, and for similar purposes, matcher-guides T T will be arrangedadj ustably upon the bed B, as shown in Fig. 3.

It will be observed that the pulley 6, with its pinion f, and theconnected gearing for actuating the intermediate gear, m, and upperroll-gears, a n, are all mounted in one of the arms G of the frame F, soas to be adjustable therewith.

By arranging the upper and lower rolls to be driven by belting andgearing independently from opposite sides of the machine I am enabled toprovide for the necessary vertical adjustment of the cutter-head andupper rolls without employing expansion-gear trains and owing to thepeculiar way of gearing the front and back upper roll-gears by means ofa double intermediate gear having a bearing on one of the cutter-headmandrel-boxes I can at the same time drive the cutter-head by belting atboth ends. This arrangement results in giving a very strong, positive,and

durable feed, which is operated by a single tightening-lever, as beforeexplained, and enables the cutter-head to be rotated smoothly and withgreat power.

That I claim as my invention, and desire to secure by Letters Patent, is

1. In a planing-machine having upper and lower feedu'olls drivenindependently by a belt and gearing on opposite sides of the machine,the combination, with the front and back upper roll-gears, n n, of anintermediate gear, m, arranged to rotate upon an annular bushing, 19,fitted to the outer end of one of the cutter-head mandrel-bearings,whereby the cutter-head mandrel is enabled to carryapulley at each end,substantially as described.

2. In a planingmachine, the combination of the main frame A, havinginclined guideways H H on each side, the lower feed-rolls, O O, mountedin journal-boxes supported in said main frame, the vertically-adjustableframe F, having guide-arms G G, the Vertically-inclined screw-shafts II, having gears J J, the transverse shaft- L, having pinions K K, thecutterhead E, and upper feed-rolls, D D, mounted in said adjustableframe F, and belting and gearing on opposite sides of the machine fordriving the upper and lower feedrollsindependently,substantially asdescribed In testimony whereof I affix my signature in presence of twowitnesses.
